NOTE:
“Ducting has a strong effect on the air flow, noise and energy use of the fan. Use
the shortest, straightest duct routing possible for best performance, and avoid
installing the fan with smaller ducts than recommended. Insulation around the
ducts can reduce energy loss and inhabit mold growth. Fans installed with
existing ducts may not achieve their rated air flow.”
Ensure duct joints and exterior penetrations are sealed with caulk or other similar
material to create an air-tight path and to minimize building heat loss and gain
and reduce the potential for condensation.
Place/wrap insulation around duct and/or fan to in order to minimize possible
condensation buildup within the duct, as well as minimize building heat loss and
gain.
* 5 Feet insulation is required
only in the areas where outdoor
temp erature drops below
DUCT SIZE:
RMF-4 : Ø4” duct
RMF-5 : Ø5” duct
RMF-6 : Ø6” duct freezing point during the year
NOTE:USE AS FEW ELBOWS AS POSSIBLE
